Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in providing efficient resource utilization and quality of service for growing data-intensive services like social networking, particularly in managing shared multimedia data across user equipment and network elements, especially when users are roaming outside their home network.
Innovation Solution
An apparatus and method that store and manage a mobile context of user equipment, including information on Home NodeBs, allowing these nodes to act as replica servers for shared data, enabling efficient data replication and access, even when users are outside their home network, by utilizing a transceiver, memory, and controller to connect user equipment to the Internet and cellular networks, and allowing network elements to belong to closed subscriber groups for optimized data delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Home NodeBs store and replicate shared data locally, then data access efficiency improves and macro cell resource usage decreases, but network complexity and data synchronization requirements increase
Solution Approach 1:
The patent divides the network into Home NodeB units, each capable of independently storing and serving replicated data. This segmentation allows distributed data access without centralized coordination for every read operation, improving efficiency while managing complexity through modular architecture
Solution Approach 2:
The patent implements data replication where multiple Home NodeBs maintain copies of shared data. This copying approach enables local data access at any replicated node, dramatically improving access efficiency while the standardized replication protocol manages the complexity of maintaining multiple copies
2Reliability
If users can access shared data while roaming outside home network, then service continuity improves, but network resource consumption and signaling overhead increase
Solution Approach 1:
The patent pre-replicates shared data to multiple Home NodeBs before users need to roam. This preliminary distribution of data ensures that when users move outside their home network, the data is already available at nearby nodes, maintaining service continuity without requiring real-time network resource consumption for data retrieval
Solution Approach 2:
The patent introduces a roaming coordination mechanism that acts as an intermediary between roaming users and their home network. This mediator manages data access requests during roaming, optimizing network resource usage by routing requests efficiently and minimizing signaling overhead through intelligent request management
3Ease of operation
If macro cells handle all data traffic, then network management is simplified, but resource utilization efficiency and quality of service for data-intensive services deteriorate
Solution Approach 1:
The patent segments data traffic handling from centralized macro cells to distributed Home NodeBs. Each Home NodeB independently serves local data requests, reducing the burden on macro cells and improving overall resource utilization efficiency while maintaining manageable complexity through standardized interfaces
Solution Approach 2:
The patent introduces a new dimension of data access by enabling users to connect to Home NodeBs in addition to macro cells. This creates a two-dimensional access architecture where users can switch between macro cell and Home NodeB access points, improving resource utilization by distributing traffic across multiple network elements
